Abstract Photocatalysis activated by visible light remains highly challenging. Here, we report novel MoSe2/ZnO/ZnSe (ZM) hybrids fabricated via a simple hydrothermal method for photocatalytic reduction of Cr(VI) under visible light irradiation. ZM hybrids show improved photocatalytic reduction ability under visible light irradiation compared to pure ZnO owing to good visible light absorption and rapid electron transfer and separation. The ZM hybrid shows the highest Cr(VI) reduction rate of 100%. Moreover, the photocatalytic Cr(VI) reduction process is mainly controlled by photoinduced electrons.

MoSe2/ZnO/ZnSe 杂化物可在可见光照射下有效还原 Cr(VI)

摘要 可见光激活的光催化仍然极具挑战性。在这里，我们报告了通过简单的水热法制造的新型 MoSe2/ZnO/ZnSe (ZM) 杂化物，用于在可见光照射下光催化还原 Cr(VI)。由于良好的可见光吸收和快速的电子转移和分离，与纯 ZnO 相比，ZM 杂化物在可见光照射下表现出更好的光催化还原能力。ZM 混合体显示出最高的 Cr(VI) 还原率为 100%。此外，光催化 Cr(VI) 还原过程主要受光生电子控制。
